Operation description
The skid control ECU determines vehicle condition by receiving signals from the speed sensor, yaw rate
and deceleration sensor and steering angle sensor. The skid control ECU controls engine torque with the
ECM, vehicle position with suspension control ECU via CAN communication, and oil pressure with the
pump and solenoid valve. The warning light comes on and the buzzer sounds when the system is
operating.
2.ABS with EBD & BA & TRAC & VSC OPERATION
a. Skid control ECU calculates vehicle stability tendency based on the signal of sensors, speed sensor,
yaw rate and deceleration sensor and steering angle sensor. And it judges whether the control of
engine output torque by electronic control throttle and of wheel brake pressure by brake actuator
will operate or not by the calculation results.
b. The SLIP indicator blinks and the VSC buzzer sounds to inform the driver that the VSC system is
operating. The SLIP indicator also blinks when TRAC is operating, and the operation being
performed is displayed.
3.FAIL SAFE FUNCTION
a. When a failure occurs in the ABS with BA & TRAC & VSC systems, the ABS warning light and
the VSC warning light turns on and the ABS with BA & TRAC & VSC operations are prohibited.
In addition to this, when there is a failure that disables the EBD operation, the brake warning light
also comes on and the EBD operation is prohibited (see FAIL
-SAFE CHART ).
b. If some control is prohibited due to a malfunction during it's operation, that control will be cut off
gradually not to change stability of vehicle suddenly.
4.PRE-COLLISION BRAKE ASSIST SYSTEM (w/ PRE-COLLISION BRAKE ASSIST SYSTEM)

HINT:
If you cannot add the listed amount of fluid, do the following:
1. Install the refill plug.
2. Allow the engine to idle with air conditioning OFF.
3. Move the shift lever through entire gear range to circulate fluid.
4. Wait for 30 seconds with the engine idling.
5. Stop the engine.
6. Remove the refill plug and add fluid.
7. Reinstall the refill plug.
4.FLUID CIRCULATION
a. Allow the engine to idle with the air conditioning OFF.
b. Move the shift lever through entire gear range to circulate fluid.
5.FLUID TEMPERATURE CHECK
a. With hand-held tester
1. Connect the han
d-held tester to the DLC3.

2. Select the tester menus: OBD/MOBD, ENGINE, DATA LIST and A/T.
3. Check A/T OIL TEMP.
4. Allow the engine to idle until the fluid temperature reaches 46°C (115°F).
b. Without hand-held tester (Using D shift indicator)
1. Create a short circuit between CG (4) and TC (13) of the DLC3 terminals using SST (09843-
18040).
2. Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.
3. The D shift indicator on the combination meter comes on for two seconds when the
combination meter begins to detect the fluid temperature.
4. The D shift indicator comes on again when the fluid temperature reaches 46°C (115°F) and
blinks when it exceeds 56°C (130°F).
c. For vehicles with air suspension (Using D shift indicator)
1. Create a short circuit between CG (4), OPA (11) and TC (13) of the DLC3 terminals using
SST (09843-18040).
2. Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.
3. The D shift indicator on the combination meter comes on for two seconds when the
combination meter begins to detect the fluid temperature.

28.SUPPORT AUTOMATIC TRANSMISSION ASSY
a. Support the automatic transmission assy with a transmission jack.
29.REMOVE ENGINE REAR MOUNTING MEMBER
a. Remove the 4 bolts and separate the engine rear mounting member.

ACTIVE TEST
Performing the ACTIVE TEST using the hand-held tester allows the meters, indicators and so on to operate
without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to shorten
labor time.
It is possible to display the DATA LIST on hand-held tester during the ACTIVE TEST.
a. Connect the hand-held tester to DLC3.
b. Turn the ignition switch to the ON position.
c. From the display on tester, perform the "ACTIVE TEST".

psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found,
check the heater core, cylinder block and head.
2.CHECK ENGINE COOLANT LEVEL AT RESERVOIR
a. Check that the engine coolant level is between the LOW and FULL lines when the engine is cold.
If the engine coolant is low, check for leaks and add "TOYOTA Super Long Life Coolant" to the
FULL line.
If "TOYOTA Super Long Life Coolant" is not available, use a similar high quality ethylene glycol
based non-silicate, non-amino, non-nitrite and non-borate coolant with long-life hybrid organic acid
technology. Do not substitute plain water for engine coolant.
3.CHECK ENGINE COOLANT QUALITY
a. Remove the radiator cap.
b. Check if there are any excessive deposits of rust or scale around the radiator cap and radiator filler
hole, Also, the coolant should be free from oil.
HINT:
If excessively dirty, clean the coolant passage and replace the coolant.
c. Reinstall the radiator cap.
